Abstract (en)
[origin: WO2019108723A1] The disclosed technology relates to a dispersant composition comprising the reaction product of a polyolefin acylating agent and a polyamine having a sterically hindered head group. In addition, the technology relates to lubricating compositions containing the dispersant composition and an oil of lubricating viscosity, as well as methods of employing the lubricating composition in an engine and engine oils. Lubricating oils containing the dispersants of the disclosed technology simultaneously achieves seal compatibility, wear, deposit, varnish and corrosion control while also maintaining fuel economy performance over a broad temperature range.
